One big problem — in photos that were taken of the incident, the camera appears to be in the photog’s hand … not in his bag.

The police report also notes that the photog didn’t sustain any “bruises or lacerations.”

Cops tell detectives will decide if the case is worth turning over to the State’s Attorney — who will decide whether to prosecute Lambert. If convicted, Lambert could face up to one year in jail and a $1,000 fine.

After yesterday’s clash — Lambert went right to his Twitter account and posted, “I lost my temper for a sec but wow it felt great lol MIAMI!!!”
